Although the origins of the South African Ndebele are shrouded in mystery, they have been identified as one of the Nguni tribes. The Nguni tribes represent nearly two-thirds of South Africa's Black population and can be divided into four distinct groups; the Central Nguni (the Zulu-speaking peoples), the Southern Nguni (the Xhosa-speaking peoples), the Swazi people from Swaziland and adjacent areas and the Ndebele people of the Northern Province and Mpumalanga.
